Simulations of the flocculent spiral M33: what drives the spiral structure?
C. L. Dobbs, A. R. Pettitt, E. Corbelli +1
We perform simulations of isolated galaxies in order to investigate the likely origin of the spiral structure in M33. In our models, we find that gravitational instabilities in the…
The origin of the structure of large-scale magnetic fields in disc galaxies
C. J. Nixon, T. O. Hands, A. R. King +1
The large-scale magnetic fields observed in spiral disc galaxies are often thought to result from dynamo action in the disc plane. However, the increasing importance of Faraday dep…
The frequency and nature of `cloud-cloud collisions' in galaxies
C. L. Dobbs, J. E. Pringle, A. Duarte-Cabral
We investigate cloud-cloud collisions, and GMC evolution, in hydrodynamic simulations of isolated galaxies. The simulations include heating and cooling of the ISM, self--gravity an…
The dependence of stellar age distributions on GMC environment
C. L. Dobbs, J. E. Pringle, T. Naylor
In this Letter, we analyse the distributions of stellar ages in Giant Molecular Clouds (GMCs) in spiral arms, inter-arm spurs, and at large galactic radii, where the spiral arms ar…
The Exciting Lives of Giant Molecular Clouds
C. L. Dobbs, J. E. Pringle
We present a detailed study of the evolution of GMCs in a galactic disc simulation. We follow individual GMCs (defined in our simulations by a total column density criterion), incl…
Giant Molecular clouds: what are they made from, and how do they get there?
C. L. Dobbs, J. E. Pringle, A. Burkert
We analyse the results of four simulations of isolated galaxies: two with a rigid spiral potential of fixed pattern speed, but with different degrees of star-formation induced feed…
